APPARATUS FOR MANUFACTURING LI NOLEUM.

SPECIFICATION forming part of Letters Patent No. 535,452, dated March. 1.2, 1895. Application filed December 29, 1894. Serial No. 533,309- (No model.)

To all whom it may concern.-

Be it known that I, DAVID N. MELVIN, of Linoleumville, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Apparatus for Manufacturing Linoleum; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to an improvementin apparatus for manufacturing linoleum and it consists in certain novel features of construction which will be hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a side elevation of a press employed in aflixing the tesserze of linoleum to the canvas backing. Fig. 2 is an end elevation of the same, and Figs. 3, 4, 5, 6 and 7 are detail views showing the cutting block holder and plunger in different positions.

A, represents a frame the length of which approximately corresponds with the usual width of canvas employed in the manufacture of linoleum. Over the body of the frame is a superstructure comprising in the main a track 1 extending parallel with the bed of the frame,and supports 2, 2, for holding this track in its elevated position. Press 3 is constructed to travel upon this track 1 across the bed of the frame.

B is a holder for retaining the tesserae and canvas in position relative to each other while the initial, pressure is applied to the tesserae, to affix it to the canvas or flexible foundation. This holder B comprises a plate having small pins 4, 4, protruding from its upper face.

0, is the block containing the tesserae.

The holder B, is placed upon the bed of the frame as indicated in Figs. 1 and 2 with its toothed face upward. The canvas 5 is drawn across this toothed holder B after the manner indicated in Fig. 1. AblockC filled with tesserae is placed beneath the press 3. A plunger 6 having fingers 7, 7, therein which pass through holes 8, 8, in the block 0, to discharge the tesserte in the block is forced down by the press with sufficient pressure to impale the tesserae and the canvas upon the pins 4:, 4, of the holder B and if necessary a slight additional pressure might be applied after the plunger is removed to insure the adhesion of the tesseree to the canvas. The plunger is then raised and the block 0 and plunger 6 are removed, after which the canvas withits tesserae applied is lifted from the pins 4, 4, and the canvas is moved on toward the press, not shown, which gives the final pressure and a new surface of canvas is presented for the application of more tesserze. If the plunger is not as wide as the canvas it is moved its width along the track to give another pressure. This lifting of the canvas and tesserze referred to, may be accomplished in any convenient manner, by hand, or by any improved mechanism. I have devised the following: A pair of arms 8, 8, are pivoted at their inner ends preferably at a common center 9, and they are disposed in such a manner that theirfree ends reach beyond the edges of the frame, where they are provided with rollers 10, 10, which extend parallel with the edges of the bed from one end of the frame to the other and their ends are journaled in the free ends of arms 8', 8. Avertical sliding prong 12, 12, at each end of the frame is guided in its movement in boxes 13, 13, and the upper ends of these prongs engage the arms 8, 8, and raise them to elevate the rollers and lift the canvas and tesserae from the pins, when the prongs are elevated, a foot lever 14, being fulcrumed on the frame and connected with the prongs to operate them when it (the foot lever) is depressed at its tread end. By this mechanism the material is quickly and easily raised from the press and the weight of the mechanism and canvas supported thereon is sufficient to return the parts to their normal position. A final pressure may be applied in the usual manner to make the tesserze adhere permanently to the canvas and to one another at their edges.

To briefly restate the operation I draw the canvas or flexible foundation across the table over the holder and then impale the tesserae and canvas upon the pins and if necessary press the tesserze until they adhere sufficiently to insure their retention in place upon the canvas. Subsequently the canvas with the tesserae thereon is lifted or removed from the pins and a final finishing pressure is applied which completes the linoleum.

Slight changes might be made in the form ICO and arrangement of the mechanism described and in the steps of the process followed without departing from the spirit and scope of my invention and hence I do not wish to limit myself to the exact construction herein set forth, but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an apparatus for the manufacture of linoleum, the combination with a frame, of a holder adapted to be placed on the bed of the frame, said holder having pins, and means for impaling a canvas backing and tesserze upon the pins, substantially as set forth.

2. The combination with a frame, ofa holder placed thereon and having pins protruding from one face thereof upon which the canvas backing and tesserze are adapted to be impaled, and mechanism for lifting the canvas and tesserze from the pins, substantially as set forth.

3. The combination with a frame, of a holder adapted to be placed thereon, said holder having pins which protrude from one face thereof and upon which the canvas and tesserae are adapted to be impaled, pivoted arms carrying means at theirends to lift the canvas and tesserze from the holder, and means for raising the arms, substantially as set forth.

4. The combination with a frame, of a holder having pins on which the canvas and tesserae 5. The combination with a frame, a superstructure and a press carried by the superstructure, of a holder having pins thereon on which the canvas and the tesserae are adapted to be impaled, a block adapted to contain tesserze, a plunger for impaling the tesserae on the pins of the holder when pressure is applied from the press, substantially as set forth.

6. The combination with a frame, a superstructure, and a press carried on the superstructure, of a holder having pins thereon on which the canvas and tesserte are adapted to be impaled, a block adapted to contain tesserze, a plunger for impaling the tesserze on the pins of the holder when pressure is applied from the press, and means forlifting the canvas and the tesserae from the press, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

DAVID N. MELVIN.
